Title: Telephony-based speech recognition for providing information for sorting mail and packages
Inventor: SKONBERG CARL M
IPC: G10L13/04
Filed: 2001-12-05
Abstract: The present invention relates to a telephony-based speech recognition system for sorting packages (142) and letters. The invention includes a wireless telephony set (102) in communication with a computer (114) through a telephony system (108) or network. Sortation information spoken by a user (118) is sent by the wireless telephony set (102) to a speech device or modem (106). A  signal containing the spoken sortation information is sent by the speech device or modem (106) through the telephony system (108) or network to a computer (114). A stored set of instructions such as a speech recognition program interprets the signal to obtain the spoken sortation information. The computer (114) generates a return signal, such as a data signal, an encoded voice signal, or both, in response to the spoken sortation information. A  second modem (110) encodes the return signal and sends the return signal through the telephony system (108) or network to the speech device or modem (106). The speech device or modem (106) decodes the return signal into a data signal (132) for output to a local computer (116) and a voice signal (133) for output to the user (118).

Abstract: A programmable IF bandwidth is achieved in either a transmitter or receiver using fixed bandwidth filters. A minimum of two IF frequencies are used. A fixed bandwidth filter that is equal to or greater than the desired IF bandwidth is used at each IF. The Local Oscillators (LO's) are tuned to frequency convert the desired signal to a frequency that is offset towards o ne bandedge of the fixed IF filters. A first mixer and LO relocates the desired signal to one end of a first fixed IF filter. A second mixer and LO relocate s the filtered signal to the opposite end of a second IF filter. The desired bandwidth is obtained as the sum of the frequency offset of the desired sign al from the nearest bandedge of the first IF filter and the frequency offset of the desired signal from the opposite bandedge of the second IF filter.</SDOA B>
